CAR-COUPLING.`

SPECIFICATION forming part of Letters Patent No. 476,958, dated June 14, `1892.

Application filed January 27, 1892. Serial No. 419144@ (N0 IIlOdL) ,o all whom it may concern.:

Be it known that I, PHILLIP IIIEN, a citizen of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Car-Couplers; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, wherein- Figure l is a horizontal section of a coupler embodying my invention, taken on the line a: x of Fig. 2. Fig 2 is a vertical sect-ion of the coupler, taken on the line y y of Fig. l. Fig. 3`is an enlarged end view of the vibrating locking-block, looking in the direction of the arrow in Fig. 4, Fig. l is an enlarged front elevation of the vibrating locking-block, and Fig. 5 is a detached view of the unlocking-pin for actuating the locking-block.

Like symbols designate like parts wherever they occur.

The invention relates to that class of couplers commonly called twin-jaw couplers, whether the same are formed with pivoted nose or knuckles provided with a pin, as in the Janney type, or with solid journalbear ings, as in the Browning type, though forpurposes of illustration, and without any intention of limiting the invention, I have chosen the Janney type, having' a pivot-pin for the pivoted nose or buckle.

The object of the present invention is to facilitate and render certain the coupling and uncouplingof the devices, cause the movement of the knuckle in nncoupling to set the lockingdilock for the subsequent coupling operation, and to relieve the unlocking-pin or means for actuating the locking-block in uncoupling from the control of the lockingblock after said pin has performed its function, whereby the use of keepers on the lockingpin are avoided and sufiicientslack in the chain between the usual pin-lever and unlocking-pin is secured.

To this end the main feature of my invention, generally stated, consists in the combination, with a pivoted knuckle or nose, of a vibratinglockingblock having two reverselyinclined faces which engage the tail-piece of the knuckle, whereby the outward movement of the knuckle in uncoupling throws thelockn ing-block forward upon the tail-piece,so that the locking-block will drop into its first oram.

ing-block, so'that it is not thereafter controlled by the subsequent movements of the locking-block derived from the knuckle.

There are other minor features of invention, all as will hereinafter more fully appear.

I will now proceed to describe my invention more fully, so that others skilled in the art to which it appertains may apply the same.

In the drawings, A indicates the usual hol low stem of the draw-bar, provided with the head B, having the guard-inger O, and the journal D for the pivoted nose or knuckle E, said nose having a tail-piece e, all of which may be of any approved construction. Within the head, at opposite points, are suitable pierced abutments l l"b for the reception of a journal-pin 2, on which vibrates a lockingblock 3, and the abutment la, adjacent to the guard-finger O, is also pierced vertically, as at Z7, for the reception of the unlockingpin 4,

or the pin `by which the vibrating locking block is moved in uncoupling.

3 indicates the Vibrating lockingblock, which is of any irregular form adapted to provide a vertical face 5, which shall engage the tail-piece e when the coupling is made, as in Fig. l, a forward incline G,whieh permits the block to ride upon the tail-piece c when said tail-piece moves inward, and a rear and reversely-arranged incline 7, which engages the tail-piece e in its outward movement and tilts the locking-block 3 forward. In addition to the said forward and rear inclines 6 and 7, the wing 8 of the locking-block adjacent to the guard-linger C is formed with a recess or open seat 9 for the reception of a lug, offset, or its equivalent on one side of the unlocking-pin 4.

4 indicates the unlocking-pin, arranged in the vertical pinslot Z1, adjacent to the guardfinger C, and provided with a lug or offset 4C,

adapted to engage the locking-block and lift thesame when the unlocking-pin is raised by its lever, (not shown,) to which it is connected by the usual chain, as indicated in dotted lines in Fig. 2.

The construction of the several devices belng substantially such as hereinbefore specified, their operation will be as follows: The parts being in the position shown in Fig; l, (which is the coupled position,) in orderto uncouple, the unlocking-pin 4 is raised to actuate thelocking-bloek to throw it up and back to permit the escape of the tail-piece cof the knuckle E. The unlocking-pin 4 is then vreleased and. falls back into its first position, as shown in dotted lines in Fig. 2, and is not thereafter controlled by thesubsequent move- In the act of uneoupling and as the tail-piece e moves outit ystrikes the rearincline 7 of the vibratingloeking-block and rocks the said block forward or revolves toward the effective end of the coupling until said block rests on the tailpiece, finally returning to its first position as the tail-piece escapes forward, so that the locking-block is left .in position to couple up on the inward movement of the tail-piece e. In coupling up, the knuckle and tail-piece being in position,i(shown in dotted lines Fig.4

1,) the tail-'piece in its inward movement will strike the forward incline 6 and cause the 'I claim, and desire to secure by Letters Patent, iS v 4o l. In a car-coupling, the combination, with a pivoted knuckle or nose, of a vibrating locking-block having reVersely-inclincd faces, which engage the tail-piece of the knuckle, substan tiallyas and for the purposes specified. 45 2. In a car-coupling, the combination, with a pivoted knuckle, of a vibrating lockingblock having a rear incline adapted to engage the tail-piece of the'knuckle, whereby the tailpiece in its outward movement causes the for- 5o ward vibration of the locking-block, substantially as and for the purposes specified.

3. In a car-coupling, the combination, with a vibrating 'locking-block provided with an incline adapted to engage the tail-piece of the 55 knuckle to rotate said 'block forward-on the vtail-piece and having a recess 9, of an unlock- January, 1892.

`Corrections in Letters Patent No. 476,958.

It ie hereby eerrined than inLereere Parent Ne. 476,958, greeted June 14, 1892, epee the application of Phillip Hien, of Chicago, Illinois, for an improvement in Oar- Couplings,77 errors appear in the printed specication requiring correction, as follows In line 31, page l7 the Word buckle 7 should read knuckle and in lines 53-54, same page, the Word uncoupling should read coupling and that said Letters Patent should beread with these corrections therein that the same may conform to the record of the case in the Patent Oice.
